FGB and glaucoma: Interestingly, although only significant in the comparison of ICL vs. glaucoma, from the total number of dysregulated proteins, FGB was found downregulated in both pathologies when comparing to ICL samples (ICL vs. cataracts p-value 0.053, and ICL vs. glaucoma p-value 0.021), suggesting the potential of this protein as a biomarker of eye pathology.
